Benefits of technology

[0004] It is an object of the present invention to provide an improved vanadium material with a high capacity for sorbing heavy metals and heavy metal compounds.

Problems solved by technology

Most of these heavy metals are toxic to humans and animals.
In particular, elemental mercury and mercury compounds such as mercury chlorides are thought to compromise the health and mental acuity of young children and fetuses.
While a variety of adsorbents are available for capture of heavy metals (in particular mercury), these adsorbents tend to have low capacities and are easily deactivated by other components in the gas stream, such as sulfur oxides.

example

[0038] The following example illustrates preferred sorbent materials and methods of making the same in accordance with the present invention. This example should not be taken as limiting the scope of the present invention in any way.

[0039] In this example, a sorbent material according to the present invention was prepared by forming a solution comprising 17.816 g of LiOH.H2O and 77.229 g of V2O5 dissolved in 60 g of deionized water. A separate dispersion was prepared containing 60 g of deionized water, 30 g of alumina (DISPAL), 60 g of expanded perlite, and 20 g of calcined Kaolin or more generally calcined clay, or more specifically meta Kaolin. The solution and dispersion were mixed together forming a thick, paste-like material. This material was extruded through a ⅛ inch die and dried overnight at 248° F. The next day, the extrudate was crushed so as to form a granular material that could be passed through a 20-40 mesh sieve.

[0040] The material was then tested for efficacy in r...

Abstract

A composition comprising a vanadium oxide compound and an alkali metal promoter loaded onto a porous support material is disclosed. Methods of making and using the composition to remove heavy metals or heavy metal containing compounds from a fluid stream are also provided. Such methods are particularly useful in the removal of mercury and mercury compounds from flue gas streams produced from the combustion of hydrocarbon-containing materials such as coal and petroleum fuels.

Description

[0001] The invention relates to a composition and method for removing heavy metal contaminates from fluid streams. In one aspect, the invention relates to a method of preparing such composition. In yet another aspect, the invention relates to a process for removing heavy metal contaminates, such as mercury and mercury compounds, from flue gas streams produced from the combustion of hydrocarbon-containing materials. BACKGROUND OF THE INVENTION [0002] Heavy metals are released during the combustion process of many fossil fuels and / or waste materials. These heavy metals include, for example, arsenic, beryllium, lead, cadmium, chromium, nickel, zinc, mercury, and barium. Most of these heavy metals are toxic to humans and animals. In particular, elemental mercury and mercury compounds such as mercury chlorides are thought to compromise the health and mental acuity of young children and fetuses. [0003] Furthermore, there is every indication that the amount of mercury, and possibly of othe...
